THRESHING-MACHINE FEEDER.

Letters Patent. Application filed March 14,1906. Serial No. 306.052.

No. 867,829. Specification of Patented Oct. B, 1907.

To all whom it may concern:

Be it known that I, DANIEL Molvon, a citizen of the United States, residing at Crookston, in the county of Polk and State of Minnesota, have invented a new and useful Improvement in Threshing-Machine Feeders, of which the following is a specification.

My invention is in the nature of an improved device for feeding the bundles of grain to a threshing machine, and it consists in novel means for facilitating the feed of the bundles and for cutting the same and loosening up and uniformly feeding the same to the threshing cylinder as hereinafter fully described with reference to the drawing, in which Figure l is a side elevation from one side and Fig. 2 is a side elevation from the opposite side. Fig. 3 a vertical longitudinal section. Fig. I4 is a horizontal section on line 4-4 of Fig. 3. Fig. 5 is a vertical section on line 5-5 of Fig. 3. Fig. 6 is a perspective view showing a portion of the straw loosening lingers. Fig. 7 is a detail of one of the retarding blades. Fig. 8 is a detail of the spreader and Fig. 9 a detail of driving gears.

Referring to Figs. 3, 4 and 5, A A are two endless carrier belts which are arranged nearly horizontal and feed the bundles of grain toward the threshing cylinder X. These carrier belts are constructed as usual in the form of slatted aprons traveling around rollers at the ends. They are arranged at an angle some distance apart at their outer ends as seen in Fig. 4 and converge toward the threshing cylinder until they are close to each other.

B B are two other which are arranged edges of the carrier and from the inner ends ofthe upright aprons, stationary vertical boards B Fig. 4, extend the balance of the length of the main carrier belts A A. These upright aprons are driven, see Fig. 5, by bevel gears b b connecting the outer rollers of the horizontal belts A with the outer rollers of the upright aprons B.

Relatively low flanges or side boards B2 B2 are arranged along the outer edges of themain carrier belts A A. The bundles of grain are thrown on to carrier belts A on both sides of the machine, passing over the side flanges B2 and falling upon the carrier belts A A and lodging against the upright aprons B B and as these latter are positively driven in the same direction with the carrier belts A it will be seen that the bundles do not hang back but are quickly carried forward by the combined travel of belts A and upright aprons B. As the bundles of grain are carried toward the threshing cylinder the bands are first cut by a rotary band cutter C, Fig. 3, then the out bundles are spread open by a spreader D acting on top of the same A horizontal series of loosening fingers E, project from below the carrier belts and catch the bundles as they fall over the ends of the carrier belts and by a horizontal and laterally oscillating movement loosen up the straw and then allow this loosened straw to fall on a retarder apron F, which runs at a relatively slower speed, and allows the straw to accumulate thereon in a uniformly thick mass which is gradually discharged over the outer edge of the threshing cylinder X, and as the latter receives a very uniform feed the cylinder is not allowed to either speed or choke.

I will now describe the special construction and means for operating these several features of my feeder.

There is a rotary cutter O, Fig. 3, for each carrier belt' A and these cutters are on a common shaft o which, see Fig.. l, has outside the casing a band pulley x2 connected by a belt x/ with a pulley on the end of the threshing cylinder, a belt tightener x3 serving to keep belt af taut.

The rotary spreader I), Fig. 3, consists of a series of hook shaped blades set around a shaft d, the blades being offset alternately in opposite directions as seen in Fig. 8, so that as they rotate they will spread or separate the straws laterally from each other. This spreader is driven by extending its shaft d through the casing and providing it, see Fig. 2, with a rigidly attached sprocket wheel d3 which is connected by a chain belt d with a smaller sprocket wheel d2 on the end of the cutter shaft o. On the same end of the spreader shaft d with large sprocket d3, see Fig. 2, is a small sprocket e which through chain belt e/ turns a sprocket e and this sprocket operates three parts, viz.: the carrier belt A, the loosening fingers E-and the retarder apron F as will be presently described.

The loosening fingers E, see Figs. 3, 4 and 6, project in ahorizontal series between the discharge end of the carrier belt A and the receiving end of the retarder apron F and their function is to stir from underneath the cut bundle as it is falling and while being spread open at the top, by spreader D. The loosening fingers are, see Figs. 6 and 3, short rock shafts journaled in a stationary bar e3 and have cranked front and rear ends and the rear cranks enter holes in a reciprocating bar e4 so that as this bar reciprocates the fingers are oscillated laterally to tear apart and loosen up the straw of the bundles. To reciprocate bar e4, see Fig. 4, it is connected to a crank pin e5 on a bevel wheel e6. wheel meshes with a bevel wheel e7 at right angles to it. Bevel wheel e7, see Fig. 9, Kis rigid Awith a straight toothed gear E2 which meshes with a straight toothed gear E above and a straight toothed gear E3 below. The intermediate straight toothed gear E2 is rigid with the sprocket wheel e2 which receives power from the chain belt ef, as seen Fig. 2. This description it will be seen traces the path of the transmission of power through the driving mechanism for the loosening teeth and the same gear E2, see Fig. 9, meshing with gear E slatted aprons orl endless belts in vertical planes along the inner belts A A at the outer half thereof This bevel a lever 1/2 is iulcruined on each side of the casing and has an elbow `1/3 that passes through the curved `slots `1/ and connects with the traine oi the retarder apron, a not ehed arc bar y and spring locking lmltj/scrving tohold-the retarder to any desired adjustment as to elevation and thereby also allowing the retarder to have a greater or less retarding etect according to the angular position which it occupies.

I claim be driven by one driving mechanism at one end.

again now to Fig. 9, the intermediate driving gear E2 in meshing with the gear E3 below it, turns the roller F, which is mounted on the saine shaft with gear E3, and this roller F is., see Fig. 3, the driving roller for the retarder apron F. This retarder apron l.

.l ust below the retarder apron F is a chaff and grain board H, Fig. 3, on which the shattered grain falls that and at its rear end is hinged at h to a ian case which has a fan G that delivers a blast over the grain board and blows the grain and detached heads and chaff into the cylinder. This fan is driven, see Fig. l, by a pulley g and a crossed belt g/ from a pulley g2 on the end ol the band cutter shaft c.

In order to give access to the front of the threshing cylinder it is desirable that the grain board H and retarder apron F be gotten out of the Way, for this purpose. To accomplish this, the grain board H, see Fig. 3, is drawn back and turned about its hinge h to a pendent DANIEL MCIVOR. Witnesses .Timms E. MoN'iAGun,
